Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a geomembrane used in soil restoration engineering and a preparation method thereof. Background technique [0002] Soil is a natural resource that is difficult to regenerate, an important basis for human production activities, and a natural shelter and purification treatment site for various wastes. However, when the soil contains too many pollutants, it will affect and exceed the self-purification of the soil. When the capacity is high, it will cause changes in the composition, structure and function of the soil, and inhibit microbial activities, thereby reducing crop yield and quality, and endangering human health through the transfer and enrichment of the food chain. Therefore, it is necessary to remediate the contaminated soil. [0003] Soil remediation includes in-situ remediation and remediation by relocating contaminated soil. Removing the contaminated soil for ...
